15-21V电动工具一个新兴的技术，支持低功耗，低速高扭将是产品的趋势，也同时具备可支持低速无感，对电机要求较高设备的高效连接，同时还能提供非常全面的应用工作。

DIY家装、建筑工地、组装车间等任何需要电动工具的场景和场所。可以打木头，打钢板，打混泥土等。

1. 额定工作电压范围：15.5~21V，适合18V锂电池包平台
2. 空载转速：机械双速0-500 RPM／0-2000RPM
3. 带冲击功能，最大扭矩60Nm
4. 无刷电机速度闭环控制，电机转速调节0-30000RPM
5. 工具带有堵转（过流）保护、过热保护、低压保护等
6. 使用无刷电机比有刷电机寿命长，无火花产生，免维护，使用更广泛
7. 轻量化设计使用可充电锂电池包供电，方便携带和现场作业
8. 无刷电动工具噪音小，舒适度较高。无刷由于特性，在噪音、震动等方面具有较大优势
